Specification of Letters Patent.

Application filed March 1, 1920. Serial No. 862,477.

I '0 all whom it may concern Be it known that I, GODFREY ENGFL, Sn, a citizen of the United States, and resident 01": Brooklyn, county of Kings, and State of New York, have invented certain new and useful Improvements in Condensers, of which the following is a specification.

The objects of my present invention are to improve and'increase the eiiiciency of condensers and particularly to accomplish effective condensation with the use of a minimum amount of condensing water and without materially obstructing or retarding the flow of the vapors.

In a referred form of my invention the condensing spray is produced by an overflow chamber which operates also as a spray head and as a means for creating another spray or film and part of the triple spray or films is caught in a collecting-trough which spills a fourth set oi separate and individual sprays over the vapor inlet. Thls collecting trough is or" annular construction and is disposed about the inner wall of the condenser casing, which leaves the central portion of the casing practically unobstructed and open to permit free passage of the vapors operated upon.

Other novel features of construction combinations and arrangements of parts will appear as the specification proceeds.

In the drawing accompanying and forming a part of this specification l have illus trated a practical embodiment of the invention, but wish it understood that variations and changes may be made without departure from the true spirit and scope of the invention as defined in the appended claims.

In the drawing referred to, Figure l is a vertical sectional view of the apparatus.

Fig. 2 is a horizontal sectional view of the same on substantially the plane of line 2-2 of Fig. 1.

Fig. 3 is a plan view of the sprinkler head construction as taken on substantially the plane of line 3-3 of Fig. i.

Fig. 4 is an enlarged broken sectional view of the collecting trough.

The shell or casing of the condenser is designated 5 and the same is shown as'provided in the up er or head portion thereof with a water i at 6, and a vacuum outlet 7 and as provided at the lower end thereof with a drama outlet 8 forming a column of the proper 'ght.

Supported within the head portion of the casing is the spray mechanism consisting of a controllable overflow chamber having an annular liquid confining wall 9 and a bottom wall erforated to form a spray head 10. This ottom wall is adjustable vertically and cooperates with the lower edge of the annular wall 9 to operate as a valve. in

the construction shown, the spray head and the lower edge of the wall 9 are provided serrations 17 so as to discharge the 'verflow in streams rather than in a solid sheet, over a conical deflecting flange 31.

It will be evident that by adjusting the spray head the discharge over the upper edge andthe flow at the bottom portion of the overflow chamber may be readily governed and varied to suit different require ments, such as may be encountered in the handling of difierent vapors.

The annular wall of the overflow chamber is shown as supported by bolts 18 from a bafide plate 19 which is indicated as carried by substantially radial ribs 20 on the under side of the top of the condenser casing. This bafiie, in combination with the ribs, prevents the spray from being carried oil with the vapor.

Below the spray mechanism described is arranged an annular collecting trough shown formed by means of an annular shelf 21 engaged and clamped between two of the sections of the casing at 22 and provided with an upstanding flange 23 and a dependent flange 24, both spaced inwardly away from the inner wall of the casing. The upstanding wall is notched or serrated as indicated at 25 and similarly, the dependent wall is toothed or serrated as indicated at 26. In this particular illustration the notches in the de endent wall are in vertical alinement with t e points of the serrations in the upstanding wall as indicated in Fig. 4 and dividing ribs 27 are provided to insure separation of the streams issuing through the notches in the upper flange. This separation of the streams is further facilitated by reason of the fact that the dependent points in the lower flange register with the notches in the upper flan e so as to cause the separated streams to all from the lower points, as indicated at the arrows 28. The notches in the lower flange are preferably cut the full depth, or so far as the lower face of the shelf 21 (see Fig. 1), so as to prevent any of the vapor. from pocketing beneath the trough.

29 designates the vapor inlet shown as opening through a portion of the downwardly and outwardly flaring wall 30 of the casing and as arranged to direct the vapors on a downward curve into the casing at a point below a-nd outside of the fall from the collecting trough.

With this construction the vapor is thus directed downwardly into the annular space within the casing about the fall from the collectingtrough and is required to pass in succession, first through this curtain of liquid and thence upwardly through the spray.

from the spra head and through the curtain delivered at t e edge thereof and finally up through the s ray curtain at the upper edge of the ove 0w, chamber. thoroughly treated during such passage and the fact that the central portion of the casing is open and unobstructed, enables the fluid extracted from the vapor to pass freely to the outlet without being materially retarded. This adds greatly to the capacity of the apparatus. This construction enables the spray to be directed outwardly so as to coverthe entire .interior of the casing without any loss in efliciency because of the fact that the spraywhich contacts and runs down the sides of the casing is caught in the collecting trough and is by this trough brought inwardly away from the walls and again discharged in position to freely operate on the va or.

The condensation is facilitated by imparting a whirling motion to the spray. This is accomplished in the illustration by mounting the spray head rotatably on the lower end of the supporting stem ,13 and by providing the head on the upper face thereof with vanes or blades 32 curved or inclined to cause the water passing through and over the head to impart a rotary movement thereto. This rotation of the spray head, it will be evident, causes both the streams passing throughthe head and the spray or film passing over the edge of the head to assume a rotary or whirling motion, which results in the thorough treatment of all portions of the rising vapors.

By my invention it will be seen that the spray mechanismin the head of the con- The vapor 21s denser produces at least three separate and distinct sets of sprays or films, first, the overflow at the top whichis directed outwardly by the conical flange, second, the film issuing from between the valve faces 11 and 12 and third, the set of streams flowing through the spray head. And there is in addition to these sprays or films the fourth spray consisting of the separate streams overflowing from the annular collecting trough. These several sets of sprays arranged as disclosed and assisted by the rotary motion described, result in a particularly effective condenser operation.

This construction results in a very thorough intermingling of the condensing water with the vapor and contact with the vapors throughout a longer period of time than has heretofore been possible and without the use of deflecting plates which obstruct the flow of the vapors, thus effecting the con-' with a minimum of injection water. The serrations in the liquid confining wall insure a substantially even discharge about the periphery of the wall and the conical flange produces a film from these numerous Streams.

The rotary movement of, the spray head results in a further advantage in that it makes the spray head self-cleaning.
